The spreadsheet has an extra column (first column) in which you can enter the letter "y" in the row you want to include

Click on the arrow in the first column & scroll to choose "y":

Now you get the rows with "y", print the file by clicking on "Print Preview"
first so you can check the output.
Note: all other rows are still available; you can return them by clicking on the
arrow again & selecting "All".
